Question

Is there any advantage in using int instead of float when the number you want to store isn’t a decimal number?

eg.

int number = 10;
float number = 10;

Why would I want to use an int instead of a float here?

Answer 1

Yes, there are lots of advantages.

• Arithmetic on ints is much faster.
• ints will never suffer from precision loss.
• People reading your code will know that the variable is actually an integer.
• It will not be possible to accidentally put a non-integer in the variable
